Q: On Croc Bites
Have you been bitten by a croc before? What should you do if you've been bitten by a croc?
Jim Barker
A: The best way to avoid being bitten by crocodiles or alligators is to exercise common sense around them, don't tease or harass them, and keep a respectable distance from them. However, if the unthinkable does happen and you are bitten, what should you do? The first rule is not to panic. If the crocodile issues a warning bite, it will typically snap and then let go immediately — this is what most crocodile bites are like. The bite itself feels like a hammer blow if the crocodile is relatively large, and the severity of the wound is normally due to the crushing force delivered. Most people will naturally retreat after receiving such a bite, and the wound needs immediate hospital attention to ensure it doesn't become infected. Crocodiles have some pretty nasty bacteria living in their mouth, and a bite will drive these bacteria deep into your flesh.
